Ozone odor should smell like fresh rain falling on leaves. If it smells like strong bleach, chances are, your ozone generator is on high setting.
Too much ozone odor can cause headaches or nose irritation. There are instances that it cause too much coughing when exposed for a period of time.
When bleach or chlorine smells occurs, it means that there is high concentration of ozone in the air.
The ozone generator should be lowered down and slowly turned up to the right level. This is the case when the room or area is where smokers stay just to continue purifying the air.
There are instances when it should be turned off and ventilate the whole room to remove excess ozone odor. This is to avoid potential health risk to human and animals as well as plants occupying that room or house.
Ozone monitoring device should be installed to continuously monitor the level of ozone concentration in the air. Our nose should be enough to monitor ozone odor in the air, however, if there are other factors that affect the air such as high concentration of molds and bacteria, cigarette smoke or air freshener, ozone monitoring device is very helpful.
If the ozone generator reaches more than 0.01 ppm to 0.05 ppm, that is when it can emit strong bleach odor like smell. 0.01 ppm to 0.05ppm is the recommended amount of ozone just to purify the air and not to kill mold. Anything higher that these, occupants of the room, house or building are to be removed so as not to inhale strong ozone odorwhich is very dangerous to health.
30 minutes to an hour for a well-ventilated room to remove the strong ozone odor if you are using the small machine. If using industrial type ozone generators, it can take days to totally remove the ozone odor.
Ozone machines should also be cleaned and maintained so it can function properly. Parts should be properly cleaned or replaced to avoid high concentration of ozone when using the machine to avoid foul ozone odorand high ozone concentration.
Ozone odor should be constantly monitored so it will not reach an alarming level. Ozone level scanners should be properly installed and the bars and graphs it corresponds to must be properly explained by the technician who installed it. Ozone generators are there to kill molds and bacteria and to purify the air and not to kill you. Better be safe when using this type of machine for ozone odor.
